IMPROVEMENT IN PLOWS.

Speciflcation forming part of Letters Patent No. 46,362, dated February 14,1865.

To all. whom it may Vconter-nr.:

Be it known that I, D. F. HUMPHREY, of

Saline, in the county of Washtenaw and State of Michigan, have invented a new and Improved Plow; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others "skilled jin the art vto make and usethe same,

reference being had to the accompanying drawf A represents what may be termed the permanent landside of the plow, and B the share, secured to its front end.

C is an adjustable landside, the front endlof which is provided with ahook, a, which is fitted 4in a recess, b, in the permanent landside A,

near its front end and lower part.

In the back part` of the landside C there is fitted horizontallya screw-bolt, c, which passes through an oblong vertical slot, d, in thevpermanent landside A, and has awasher, e, upon it and a nut, f,'the washerand nut being at the innerside of the landside A.

At each side of the slot d, at the inner side of the landside A, there are horizontal grooves g, to receive projections h at the :inner side of the washer e, the latterbeing kept engaged with the grooves by the nut f.- By this-an. rangement it will be seen that when the landside C runs or bears upon the ground it may be adjusted at its back part higher or lower,

according, to the height ofthe slot d, and may besecured at any desired point within the scope of its movement'by screwing up the ff nutf. I

Bylowering the landside C, a greater pitch or rake is given the share B,"the pitch being reduced by raising lsaid landside.

I claim as new and desire to secure by Letters Patentv The movable 'or adjustable landside C, provided at or near its forward end with a hook vwhich engages with a hole in the landside A, and fixed adjustably in a vertical slot in the latter by means of the notches g, the notched washere, and the screw-bolt and nut c f, as

'described and represented.
